GENERAL HISTOLOGY

Detailed explanation-1: -The ovoid nuclei are usually placed towards basal surface. This type of epithelium is commonly adapted for secretion, absorption and protection. As a protective epithelium, it lines the minor ducts of many exocrine glands, while as a secretory epithelium it lines the stomach and uterine cervix.

Detailed explanation-2: -it absorbs nutrients from the lumen of the intestine. Simple columnar. epithelia are also located in the stomach where it secretes acid, digestive enzymes and mucous. Stratified Squamous Epithelium Stratified squamous epithelia consist of multiple.

Detailed explanation-3: -The main function of simple columnar epithelial cells are protection. For example, the epithelium in the stomach and digestive tract provides an impermeable barrier against any bacteria that could be ingested but is permeable to any necessary ions. This function is especially important in the colon.

Detailed explanation-4: -Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Detailed explanation-5: -Simple columnar epithelium: This type of epithelium is often specialized for absorption and usually has apical cilia or microvilli. These cells line your stomach and intestines.
